Motherboard FAN Sensors

Hi,
I am not sure if this happened all along, or only after I installed the CoreCenter.
My current system consist of P4 3.0 (with HT), MSI 865PE Neo2 Series Motherboard, 2GB RAM. Graphics Card is ATI 9250, 1 Creative Audigy Platimum. I have 2 SATA hdd, WD500DB and Seagate 250GB. 1 IDE WD200GB, 1 TDK 40/12/48B and Benq DW1670. The PSU is seasonic m12-2 430w, newly acquired). I did not do any overclocking, i.e. did not install CoreCenter, until recently.
After I installed the CoreCenter, out of the blue, it will trigger off the alarm that the CPU fan is not running although I can still see the fan spinning well. All the fans (CPU, 2 casing fans) in the system at that time is reported to have 0 RPM. Is it because motherboard is dying, or it is an issue of the Software that cause the senor to malfunction?
Please help. Thanks in advance.
Regards.

Uninstall Core Center completely. Can you see anything about fan speeds in BIOS (H/W Monitor)?
Install SpeedFan and Everest Ultimate (latest Trial Version) and check what they have to say about your fans.
I did install the sensor view. At the time of failure, the sensor view also display the fan RPM as 0. After I restart the server, every thing goes back to normal. Strange.
Anyway, I have uninstalled the CoreCenter, and installed the SpeedFan. Will carry on to monitor the system.

i've tried run pwmconfig and got this:
Found the following devices:

hwmon2/device is w83627thf
Found the following PWM controls:
hwmon2/device/pwm1

hwmon2/device/pwm3
Giving the fans some time to reach full speed...
Found the following fan sensors:
hwmon2/device/fan1_input current speed: 0 ... skipping!
hwmon2/device/fan2_input current speed: 0 ... skipping!
hwmon2/device/fan3_input current speed: 0 ... skipping!
There are no working fan sensors, all readings are 0.
Make sure you have a 3-wire fan connected.
You may also need to increase the fan divisors.
See doc/fan-divisors for more information.
anyway i managed to control my system fan to monitor temp1 (motherboard temp) running:
echo "180" > /sys/class/hwmon/hwmon2/device/pwm1
but i need to run it as root and pass "yes" to pwmconfig first to activate manual control
so i need a bash script to run this automatically on startup,i found this one and modified it but i need help to get pwmconfig run with "yes" before start my if...else control to launch "echo..." once temp1 reach 50 C°

3-pin Fan Sensor

I have a Neo4 Platinum with an Antec NeoPower 480W Power Supply. This power supply comes with a 3-pin fan sensor. where on the motherboard do i connect this 3-pin fan sensor???

Any free 3 pin connector [EDIT] as the poster below says not all can monitor fans speeds. Though note you don't have to install it - it's just for monitoring the PSU fan's speed.

MSI K7N2 Delta ILSR - Noisy Grinding Motherboard Fan

Hi,
The Motherboard Fan on my MSI K7N2 Delta ILSR has started to make a terrible grinding noise and I was hoping someone could offer some help on how to replace it.
Some of the questions I have are -
+ Is the Motherboard Fan screwed on or glued on?
+ Could I replace it with a suitable heatsink (no fan)?*
+ If it is glued on, what is the best way to remove it?
+ If it is glued on, could I just unplug it and stick a new fan on top of the existing one?
+ Has anyone else had this problem and if so what did you do to fix it?
* I was looking at a Zalman Motherboard Heatsink from http://www.quietpc.com/uk/vgamb.php
Thanks in advance, Jason.

Psu fan sensor

i have a new psu which has a wire for the fan sensor with a 2 pin plug attached but i cannot find anywhere to plug it into on my k7n2 board.
my question is am i blind or does this not need to be attached to the m/board being that the 2 fan points on the m/board are already being used
thanks in advance

I've just upgraded my PSU to an Antec unit. I've a few Q's of my own and thought i'd tag along rather than start a new thread.
My MSI Supplied PC Alert software has displays for System Fan , CPU Fan And PSU fan can i presume that the fan that is sitting on my Northbridge Chipset is supplying the System Fan speed.
Would it be OK to run the northbridge fan via a spare molex+adaptor and plug my Antec PSU sensor wire into SFAN1. I would think it was more important to have the CPU and NB fans on constantly and let the PSU vary the case and PSU fans - any idea's on this ??
I Think that the Antec PSU has a certain amount of logic built in and can vary the fan speeds depending on the Temp , does anybody know if it can do this independantly (with an inbuilt temp probe) or does it need to be plugged into one of the MoBo Fan pin-outs.
I can't get over just how quiet my computer is after fitting this new PSU , i keep checking to see eveything is still whirring away, it's so quiet. The (brand new) Fan supplied with my CPU is a right rattler when it starts up, it is easily the noisiest fan on the machine, possibly noisier than the 5 other Antec fans put together !
Sorry if these Q's are a bit basic , i always think it best to ask before frying anything.

No temperature sensors found and no fan sensors found

Today when I opened my iMac, I was surprised that iStat found none of the temperature and fan sensors. Yesterday, everything was working well. Coincidentally, my mac was making a loud whirring sound that gets annoying. What should I do?

I would suggest resetting the SMC first by shutting down the machine, and then unplugged ALL cables from the iMac including the AC power and letting it sit for at least 30-60 seconds.
Plug the AC power, mouse and keyboard back in and turn it back on; see if the Fans are reported in iStat now.
Post what your various temps are once you get it back up.

Motherboard fan

Does anyone know where I can obtain a new (or second hand) motherboard fan for a KT3-Ultra 2 BR (6380E) board, as mine is making an 'interesting' noise? Any help appreciated.

No Fan Sensor Found No Battery Found Doesnt Sleep when lid is closed?

I have a late 2006 model MacBook Pro and this past week the battery doesn't show up on the menu bar, so I cannot see if it's charged or not (except the LED's at the bottom which indicate it's full) but more importantly, according to iStat, there were no fan sensors found, and the fans sound like they are running full speed with no slowdown from start to sleep. And I now have to manually put it to sleep and I didn't change my preferences to do so. Before I spend what would most likely be more than what the thing is worth, I wanted to know if there's anything I can do before I take it to Apple?
I'll take whatever you can offer as I rely on this computer for school, home, and work!
Thank you so much in advance!

Hi b, and welcome to Apple Discussions.
Try an SMC Reset. Also take a look in System Profiler to see what it says about the batt condition. If neither of these help, boot from the install disc with the Apple Hardware Test on it (hold down the d key) and see if it finds any bad sensors.

Fan/sensor problem. Please help! 4SNS/1/4000000:TsOP

Hello people,
I have the fans of my Santa Rosa 2.4MBP constantly on at 6000RPM. Hope the problem is the thermal sensor... But which of them???
Apple Hardware test shows an error:
4SNS/1/4000000:TsOP
I can't send the laptop to the Apple service center, for it's pretty far away from here. And I would fix everything myself, rather then paying those guys.. I mean I am qualified enough with assembling and disassembling this MBP and changing a sensor doesn't sound as a scary task.
Please tell me it's not the logic board, that got in trouble.
Thanks!

A thermal sensor lead to the motherboard has come off (or the sensor has failed) and so it runs in 100% fans on mode 'just in case' to prevent any overheating issues.
If you're careful and competent you could check if one of the leads is off yourself but if the sensor has blown I think you'll need Apple to fix that. (Pics to help you along)

Speed Fan sensor ID's on Neo2 Platinum

Can anyone give me a clue to what the sensor labled "Remote Temp" in Speed Fan is reading?
It's got me kinda concerned, because sometimes indicates temps that are nearly as high as my CPU! & that wasn't the case until very recently.
In the "Configure" screen it reads like this:
Label Chip Sensor Sample Bus Address
Remote Temp MAX6648 Remote Temp 37C I2CNvidia SMbus $4C
Thanks!

Winbond sensor3 is not connected to any external sensor on motherboard , and any temp on this one is bogus.
The mobo has two valid connections to winbond chip nvidia-chipset & cpu , no case sensor .
Winbonds connected are :
Sensor1 chipset
Sensor2/diode cpu
In my case with SpeedFan 4.20, sensor #1 is obviously bogus as I'm reasonably certain that my chipset isn't running @ 9C... Sensor #2 has been verified as "the real deal" as CPU, however. Maybe they've been reassigned/relabeled in this version. Sensor #1 WAS cpu in version 4.17 of SpeedFan.

The MAX6648 is the sensors on the NVidia card. I never even saw that sensor until I installed my vid card and there they were.
As far as the "MAX6648" sensors go - I know that neither one of the values denote Vid core temps, which are 43-45C. As reported by temp utilities by Nvidia & Riva Tuner. Perhaps one of them is an ambient temp sensor of some sort or that SpeedFan is flat reading them incorrectly....
I know it's all academic anyway.... My "box" is reasonably dust-free, all my fans are running, there are no malfunctions (out of the ordinary anyway... it IS Windows after all!) & I don't smell the distinct odor of "electronic expiration".

Z87-G45 CPU Fan Sensor Malfunction

Seems like pretty much a non issue but none the less I want to figure this out. When monitoring fan speeds on the MSI Z87-G45 Gaming motherboard it keeps reading zero, then returns to a normal level, then reads 0. I noted this even in the motherboards on utility accessed before allowing windows to load and again using a 3rd party monitoring program. I'm going to assume its a faulty sensor but I'm just not sure. Anyone have any ideas?

Quote from: badboy2k on 19-July-14, 14:08:55
the stock coolers with Processors suck and are only meant as basic cooling (if there under load they get very hot and the fan spins at 100% which on them sounds like a jet engine) i too would change that for a good after-market one!
My I5-4590 hovers around 30C idle, and stays under 60C under gaming loads with the stock cooler ... even with more CPU intensive games, so, they do work well if everything is working correctly..... possible that his CPU fan is getting ready to fail.

Motherboard fan mount needed

Hello, I am trying to repair a family members desktop (HP Pav. 6240f). Complaint was : not able to complete boot. Machine constantly shutting down. Upon inspection machine was indeed shutting down soon into booting up. Found a problem with the motherboard. The heat sink and fan assembly had loosened from its mount. The mount had crumbled into pieces, I am assuming due to heat? My attempt at repairing the problem would be to find a replacement mount, apply paste and re-assemble. I am assuming the system shutdown was exactly what it was supposed to do. I am not a computer tech, had some electronic training in the USMC and work with my hands, figured I give it a try. I have looked on-line, but haven't come up with a replacement. I would appreciate any help available in regard to this problem THANK YOU.

Let's try to walk you through some points, as I understand it.
The CPU chip is mounted into it's Socket 775. The heatsink has thermal paste for heat transfer.
From what I see of the mount (upgrade/service manual) there are 4 posts that secure the physical heatsink/fan, called retension clips, found here. Are these want your asking about?

[Solved] Overheating/fan/sensors issues after kernel updates

Hi all,
I realise there has been a bit of correspondence on this already. I'm after some advice for my specific situation:
1. My laptop is an acer aspire 5315. I has well understood overheating issues that arrise due to BIOS problems
2. Fan control and temperature reporting worked perfectly with kernel 2.6.30, stopped working with 2.6.31 - I assume due to the well documented changes made in that release. The temperature only seems to be read once - at boot. sensors never reports a change after that; if the temperature is cold at boot the fan never get switched on. Unfortunately this happens most often.
3. I tried setting the recommended kernel option (can't relocate the post now). It didn't help :-?
4. I have tried upgrading the BIOS but the distribution from acer is a windows executable (won't run under freeDOS) and I do not have windows installed on this PC (not game to try under wine).
5. I re-installed the old kernel from my pacman cache only to find that my wireless no longer works (fan works just fine though).
I'm now totally stumped :-/
I'd like to update my bios and go with the latest kernel but can't see a way without installing windows.
This might be fixed in an ubuntu kernel release (https://bugs.launchpad.net/ubuntu/+sour … bug/453700) but I'd prefer not to do that switch... perhaps the same fix is coming to arch?
I'd accept having to pin the kernel to an earlier version but neet to get the wireless working.
help...
edit:
I've now managed to get the kernel backdated correctly (so that wireless works as well as the fan) by re-installing the kernel and firmware together.
Have configured pacman to igmore future kernel updates
If anyone has any suggestions on howto update my bios I'd be very greatful.

Hi,
Got exactly the same issue, after running for a while laptop justs goes off... going to try to regress kernel until issue is resolved
BIOS update does sound a bit extreme
MrG

Fan sensors changed? (thinkfan)

Hello all,
after some days without an update on a Thinkpad I did it yesterday and the fan spinned around. Thinkfan was'nt starting. With one of the last Arch updates the addresses of the thermal sensors were changed. I'd like to know more about it. Which part caused this change?
(My thinkfan is configured well again, that's not my question. I wanna know about the chage of addresses.)

Probably a kernel change, check /var/log/pacman.log for that.

MSI motherboard Fan headers safe voltage loads

I`m wondering what the safest Voltage/Amp/Wattage load is on these headers.
I have a lot of case/Cpu fans all with different current information, but not sure what is safe to use or not on the headers.
The coolermaster neons are marked as DC12v - 0.16 amp, my thermaltake`s are marked as DC12v - 0.18amp and just found one made by Y.S Tech marked as DC12v - 1.92 watts. And as for the CPU fans any thing from DC12 - 0.12 to 0.38.
I assume that the lower the amperage the better !
It may be a idea for MSI to include in the manuals a safe range of volt/amps loads for these headers.
And I wish more fan manufactures would supply a 12v molex to header adaptor (most do), but leave the sensor wire free, so you could if you wanted to put that to the header on the mobo.

Hi,
If I'm not mistaken the max load on the headers is 0.3A...
